Would've been fun with a little more elaborate backstory to make this a bit spookier! Some diary entries, by the ghosts you meet, maybe? Something about what the portrait signifies, why you're locked in (a deep rooted vengeance in the house's history, maybe?). Would be nice with these asylum games in particular, they have a great atmosphere otherwise, and so much laborious puzzling to go through compared to the rest.
Also, seems I get the 'High Roller' medal nodification... but it doesn't exist? Would be great if that could be added in retrospect, if it still applies when you unlocked it earlier. Anyway, nice game!
